Which is quickest?

[chipperhead]

arnt the rx's down on power from the factory anyway?

Well I'd have thought his 230bhp car was going to feel quicker then it actually was.
His car is a minter as well and really looked after so I don't think its down on what it should have.

I can tell you which one has the best engine note!

love that VR6 sound

You must be insane - have you heard a rotary on full chat with a proper exhaust?! There's no sound in the world like it

I don't know, I think my washing machine sounds very similair

I assume he meant same distance as in 1 car length before booting, 1 car length 100mph later

thats my point 1 car length at 30mph is lets say 0.5 seconds.

1 car length at 100mph is 0.2 seconds gap, therefore the car behind is closing in?

therefore the gap MUST increase otherwise it shows one car is quicker than the other.

hence the "concertina" effect in F1 where they close up and extend the gap going into a corner, but still retain (to a thousandth) the same time gap between the car in front and their car.

the problem with the 231 RX8 is the torque is too low and you have to rev the guts out of it to get the best. So off standing its not at its best.

When you consider its RWD the tables turn somewhat.

No one pulls off from idle speed anyway.

No - I don't think you're right.

Imagine if they're both pulled by a huge piece of machinery 1 mile down the road. One is pulled by a piece of rope that is one car-length longer than the other car is being pulled by. If they were both pulled at the same acceleration/speed the distance would remain the same.

The timing gap would reduce purely because they're going faster together - not because the distance has changed.

EDIT: And the concertina effect is because there the following car has to wait until he gets out of the corner before putting the power down. He cannot physically put the power down any earlier so the gap looks like it's getting smaller/bigger all the time.

maybe, but the distance x time = speed (or whatever it is) calculation holds true i think.

and with regards to the F1, he cant put the power down correct, this is not because of the car in front but grip levels (unless he is a faster driver/car) but the time different may remain at e.g 0.5 seconds, but they are 5 metres apart, but they both accelerate, the gap in metres increases but the time remains the same 0.5 second gap. therefore they are as quick as each other, but one looks like it is losing ground to the other?

Think of it in another terms. Here is an equation for distance which can be used to show it.

s = ut + 0.5at^2

There s is the distance from origin, now if both of them are 1 car length apart that means the s value is the same for both cars.

The u value is 0 as it stands for the starting velocity, so both will have 0.

t stands for time, which will be the same when looking at snapshots at different speeds.

So if all the other values are the same for both cars, this means that a (the acceleration) must be the same value.

Also it's, speed = distance / time.

So what you are saying is that as I accelerate and the distance between by front and rear wheels stays the same, that my rear wheels are travelling faster than my front wheels?!

I was going to say vr6 because 30 is quite an awkward speed and the vr6 has more torque. Whats the gap from a standing start

Dunno, we didn't try a standing start.

Easy way to end this silly mathematics argument:

If you lined up next to each other and stayed dead level, acceleration would be identical.

If you started 10 yards apart, you would expect to always be 10 yards apart as acceleration is identical. Same distance covered in the same amount of time.
